Application filed June 1, 1915. Serial No. 31,451.

improvements in a bullet deflector for can- 7 none. v

The primary object of this invention is the provision of a bullet deflector for ordnance such as a cannon-and whereby the operator will be protected from the flying bullets of the enemy, although having a free forward view for sighting the gun.

A further object of the invention is to provide a cannon attachment in the form of a revoluble .bullet shield forwardly positioned of the artilleryinans situation, the shield being operable by the artilleryman simultaneously with the gunloading, sighting and firing operations.

A still further object is to provide a mov able bullet shield. operable by an artilleryman and capable of deflecting any oncoming missiles alt ough allowing visual access through the shield for sighting and firing upon the enemy.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described,

illustrated. in the accompanylng drawings and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designatlng characters refer to corresponding parts throughout the several viewsz-Figure 1 is a side elevation of a cannon provided with the present invention, the same being illustrated in a state of rest. Fig. 2 is a transverse sectional view taken upon line II- II of Fig. 1, and Fig. is a longitudinal sectional view taken upon line IH-III of T he present invention although adaptable as a bullet shield for different forms of crdnance, is herein illustrated as operatively positioned upon a cannon mounted upon a base 11 by means of spaced supporting legs 12,

The bullet shield is revolubly mounted upon the cannon by means of a sleeve 13 journaled thereon and a collar 14 journaled upon the cylindrical forward portion 15 of the cannon of a greatly reduced diameter,

the shield consisting of two oppositely arranged obliquely positioned blades 16, V- shaped in cross section and having their forward narrower ends 17 fixed to the collar 14, while the said blades are connected adjacent their rear ends to the sleeve 13 by means of diametrically opposed brackets 18.

The sleeve 18 and collar 14: are longitudinally slidable upon their respective journaling portions of the cannon for allowing for the recoil of the gun, and opposite stop lugs 19 are provided upon the cannon forwardly of the sleeve 13 for limiting the forward movement thereof while an annular stop band 20 is positioned at the mouth 21 of the cannon for limiting the forward movement of the collar 14:, it being understood that a rearward movement of the entire shield is prevented by reason of the tapering of the cannon as at 22 in the rear of the collar 14: and extending to a point substantially at the forward limit of movement of the sleeve 13 as determined by the aforementioned stop lugs 19.

A power shaft 23 is journaled through the leg supports 12 and is provided with a balance wheel 24: upon its outer end having an operating handle 25 and whereby the artilleryman at the station adjacent the breech 26 of the cannon may readily operate the said power shaft. A driven shaft 27 is also journaled through the legs 12 and has a pinion 28 upon its forwardly projecting end, which pinion is in constant mesh with the gear toothed portion 29 of the periphery of the journaled sleeve 13. The sleeve teeth are elongated for allowing the longitudinal sliding movement of the sleeve upon the cannon while the pinion 28 remains in constant mesh therewith. An idler shaft 30 is arranged between the said power and driven shafts and is provided with a pinion 31 in mesh with a gear 32 upon the power shaft 23 and is also provided with a gear 33 in constant mesh with a pinion 34 upon the v driven shaft 27.

The speed of uch revolutions may be varied by the artilleryman so as to obtain the'desired degree of free visual access to the The invention thus provides a serviceable.

shield for protecting the lives of artillerymen during the operation of the gun and it will be noted that minor changes may be made in theinvention from those herein illustrated, such for instance, as the provision of a greater number of deflecting blades 16 and without departing from the spirit and scope of the invention as claimed.

What is claimed as new is I 1. .An attachment for cannons comprising a forwardly positioned collar and a sleeve spaced therefrom, each being revolubly journaled upon the cannon, oppositely arranged rearwardly diverging forwardly tapering blades substantially \l-shaped in cross section having their forward ends secured to the said collar, diametrically positioned brackets upon the said sleeve secured to the inner faces of the said blades, and manual revolving means for the said sleeve extending adjacent the breech end of the cannon. 2. An attachment for cannons comprising a forwardly positioned collar and a sleeve spaced therefrom, each being revolubly journaled upon the cannon, oppositely arranged rearwardly diverging forwardly tapering blades substantially V-shaped in vcross section having their forward ends secured to the said collar, diametrically positioned brackets upon the said sleeve secured to the innerfaces of the said blades, an annular stop band for the said collar arranged at the cannons'mouth, opposite stop lugs for the said sleeve, theexterior of the cannon being tapered from the rearward limit of movement' of the collar to the forward limit of movement of the sleeve and manual revolving means for the said sleeve.

3. A bullet deflecting attachment for a cannon having a forward tapered portion forwardly terminating in a reduced cylindrical portion adjacent the mouth of the cannon, and comprising a slidable collar journaledupon the said reduced cylindrical portion forwardly of said tapered portion, a stop band for the said collar arranged at the mouth of the cannon, a slidable sleeve journaled upon the cannon rearwardly of the tapered portion thereof, opposite stop lugs for the said sleeve terminating at the,

inner end of the said tapered portion, oppositely arranged rearwardly flaring deflecting blades V-shaped in cross section and having their forward tapered ends secured to the said collar, diametrically oppositely ,ar--

ranged brackets upon the said sleeve secured to the said blades, and revolving means for the said deflecting attachment."

4. A bullet deflecting attachment for a cannon having a forward tapered portion forwardly terminating in a reduced cylin drical portion adjacent the mouth of the cannon, and, comprising a slidable collar journaled upon the said reduced cylindrical portion forwardly of said tapered portion, a stop band for the said collar arranged at the mouth of the cannon, a slidable sleeve journaled upon the cannon rearwardly of the tapered portion thereof, opposite stop lugs for the said sleeve terminating at the inner end of the said tapered portion, oppositely arranged rearwardly flaring deflecting blades V-shaped in cross section and having their forward tapered ends secured to the said collar, diametrically oppositely arranged brackets upon the said sleeve secured to the said blades, supporting legs for the u said cannon, elongated gear teeth upon the said leeve, a driven shaft 'journaled in the said legs, a pinion upon the said shaft in constant mesh with the said sleeve gear teeth, a power shaft journaled in the said legs, opposite connections between the said power and driven shafts, a fly wheel at the rear end of the said power shaft and rearwardly of the cannon and ap the said fly Wheel. 1
